FLOOD-GATE.

SPECIFICATION forming parter- Letters Patent No. 791,637, dated June e,1905. Applicationrled September 26, 1904. Serial No. 226,066.

To (LM whom it may concern..- n

Be it known that I, HENRY DEARBORN MER- RILL, a citizen of the UnitedStates, residing..

This inventionrelates to automaticrHood fences or gates for luse acrossstreams and low places liabie to be Hooded in certain seasons of theyear, which will effectually prevent the passage ofl stockduring the dryseason, but which will yield and permit the passage of drift materialduring high water or Hoods without damage and be restored to its formerposition when the Hood has passed.

The invention has for its lobject to improve and strengthen theconstruction of devices of this character. A y

With these and other objects in view, which will appear as the nature ofthe invention is better understood, the same consists in certain novelfeatures of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forminga part of this specification, andin which corresponding parts are denoted by like designating characters,is illustrated the preferred form of embodiment of the invention capableof carrying the same into practical operation,

In the drawings thus employed, Figure 1 is an elevation of the improveddevice from the downstream side. Fig. 2 is a plan view of the same. Fig.3 is a section on the line 3 3 of Figi l. Fig.L 4 Ais a section on theline 4 4 of Fig. 1. Figs. 5 and 6 are enlarged detail be any distanceapart, according to the nature of the ground.` Where the stream or lowland is relatively contracted, one of the gates only willgenerallybe'required; but for wider streams -orlands two or more of thefgates may beemployed and arrangedto operate independently. For the purpose ofillustration two of the gates are shown, with anintermediate suppor'ting-post 12. The ordinary fences 13 14, of any approvedconstruction,

will/lead from the boundary-posts 10 11.

The automatic gate or fence'portion of the Y-device consists of the headmember-l5, having spaced pickets 16 and provided at the ends withU-shaped loop-bolts 17, connected to the inner faces of the posts 10 11and both sides of the intermediate post 12 by bolts 18. The ends of thehead members 15 extend past the upstream sides of the posts and arepreferably squared ,where they engage the posts and hang from theirpivot-bolts at an angle, as

shown more clearly in Fig. 5, and thus support the pickets 16 normallyin a vertical position. The-outer ends of the pivot-bolts 18 varesupported by guard-straps 19, bolted to form a water-shedding surfaceand preventing damage to the banks by drift material and ice.

The intermediate post 12 is provided with a U-shaped strap 32, extendingabove the same and between whose sides the central pivot-bolt .18. isconnected, the strap thus performing substantially the same function asthe guardstraps`19 and being, in fact, a modified form of' the same. TheU -shaped strap 32 also serves as a support for one end of an inclinedcombined ice-breaker and post-supporter 33,

the member 33 being supported and 'strengthened by a mudsill 34 andvertical stay members 35 in substantially the same manner as the members20 21 are 'strengthened and supported.

The'construction is very strong and durable "Ioo The U-shaped straps mayalso be employed,H

upon the end posts if required.

Having thus described the invention, what is claimed is- 1. In aflood-gate, spaced supporting-posts at the sides ofthe gateway-openingand one or v lmore intermediate supportingfposts, U-shaped keeper-strapsconnected to said intermediate y, posts and provided with transversepins, gates formed of head members-and spaced pickets with the adjacentends of the `head members f `provided vvitlrelongated eyes for-movablyengaging -said pins betweenzthe sides ofisaid U-shaped straptrand aguard member connected to each of saidl strapsfat the upper terminal Iofthe same and extendingat an incline therefrom and secured to the bed ofthe stream at the .upstream side of the gate.

2.i In a flood-gate, spaced supporting-posts at the sides of thegateway-opening and one or more intermediate supporting-posts,keeperstraps on the inner sides of the end posts and upon both sidesofthe intermediate posts and spaced therefrom and provided with transversepins, and gates formed of head meinbers and spaced pickets and providedwith elongated eyes movably engaging said pins.

3. In a Hood-gate, a supporting-post having an inverted-U-shapedstrapattached to its sides and -provided with a transverse pin, in

elongated eyes for movably engaging said transverse pin.

In 'testimony that I claim the foregoing as i my own I have heretoaiiixed my signature in the presence of two witnesses.
